Claims23
A dasher assembly for a softserve product dispensing machine, said assembly including:
- a foraminous cylinder for mounting for rotation interiorly of a freeze chamber of a softserve product dispensing machine;
- a helical, product pushing beater for coupling to said foraminous cylinder;
- a plurality of blades attached to the exterior of said cylinder, said blades, when in position on said cylinder forming a helix and at least dimensioned to effect movement of softserve product, when said cylinder is operatively mounted within a freeze chamber of a softserve product dispensing machine and;
- a driving portion on said foraminous cylinder for coupling to a drive for effecting rotation thereof.
A softserve product dispensing machine including a closed refrigeration system with a recirculating refrigerant path, said system including a condenser in said path having a liquid refrigerant output, a throttling expansion valve for changing state of liquid refrigerant to a gas and an evaporator having a refrigerant inlet and outlet, all serially connected in said refrigerant path,
- said evaporator including a freeze chamber having a spaced apart product inlet and outlet;
- and
- a dasher assembly in said freeze chamber for mixing the softserve product, said dasher assembly comprising;
- a foraminous cylinder mounted for rotation interiorly of said freeze chamber;
- a helical, product pushing beater coupled to said foraminous cylinder;
- a plurality of blades attached to the exterior of said cylinder, said blades forming a helix and at least dimensioned to effect movement of softserve product, when said cylinder is rotating and;
- a driver for effecting rotation of said foraminous cylinder and a driving portion on said foraminous cylinder for coupling to said driver for effecting rotation thereof.
A beater assembly for a softserve product dispensing machine, said assembly including:
- a foraminous cylinder for mounting for rotation interiorly of a freeze chamber of a softserve product dispensing machine;
- a helical, product pushing beater insert, for insertion into one end of said cylinder, said insert including a foraminous cylinder coupler,
- a mating coupling in the cylinder for mating coaction with said coupler and to lock said beater insert so that as said cylinder rotates so does the beater,
- a plurality of blades forming a helix about said cylinder and scraper blades dimensioned for scraping engagement with the interior of a freezing cylinder for whisking softserve product from said cylinder, and;
- a driving portion on said foraminous cylinder for coupling to a rotatable drive means.
